Question

72:{120:[45-(3^3-6^2:12+1^2023)]}

Answer 1

`72:{120:[45-(3^3-6^2:12+1^2023)]}`

`= 72 : {120 : [45 - (27 - 36 : 12 + 1)]}`

`= 72 :{120:[45 - (27 - 3 + 1)]}`

`= 72 : {120 : [45  -25]}`

`= 72 : {120 : 20}`

`= 72 : 6`

`= 12`

Answer 2

\(72:\left\{120:\left[45-\left(3^3-6^2:12+1^{2023}\right)\right]\right\}\)
\(=72:\left\{120:\left[45-\left(27-36:12+1\right)\right]\right\}\)
\(=72:\left\{120:\left[45-\left(27-3+1\right)\right]\right\}\)
\(=72:\left\{120:\left[45-\left(24+1\right)\right]\right\}\)
\(=72:\left\{120:\left[45-25\right]\right\}\)
\(=72:\left\{120:20\right\}\)
\(=72:6\)
\(=12\)
